SPRAY-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 400,730, dated April 2, 1889.

.Application filed January lO, 1888.

T0 @ZZ whom it may concern;

Be it known that I, JOHN BEAN, a citizen of the United States, residing at Los Gatos, in the county of Santa Clara and State of Galifornia, have invented certain new and useful Improvements in Spray-Nozzles, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in nozzles for use in connection with hose 5 and is particularly designed for spraying water and insect-destroying liquids upon plants.

The object of the invention is to so construct the nozzle that it shall throw a fine spray and shall be self-cleaning, so as to eject from it any foreign substances that may clog it by the action of the stream itself.

In the accompanying drawings, forming a part of this specification, and on which like reference-letters indicate corresponding parts, Figure l represents a sectional view of my improved nozzle; Fig. 2, also a sectional view. but at right angles to that shown in Fig. l, being on the line a: 0c thereof; Fig. 3, an end View of the nozzle; and Fig. 4L, a detail sectional view, with the plug in the reverse direction from that shown in Fig. 2.

The letter A designates the body of the nozzle, or nozzle proper, the same being constructed substantially as usual, with the eX- ception of the concave mouth B for the purpose of removing all or essentially all the metal of the body from the front side of the plug, so that the body will not interfere with the direction or course given to the shattered stream.

The letter C designates a plug of the usual kind in so far as concerns its fitting the body A, and being held therein by the nut and washer D and E This plug is bored partly through its diameter at F, and opposite this passage is concaved or recessed, as shown at G, leaving a comparatively thin curved partition or diaphragm, H, extending across the inner end of the passage. This diaphragm is also curved or convex on the side opposite said passage. In this diaphragm is a parallel slot, I, preferably tapered in crosssection, as shown, and through which the water or other liquid is ejected.

Serial No. 260,358. (No model.)

I have ascertained that when the convex side of the partition or diaphragm is placed toward. the liquid the same is discharged in the form of fine streams, which meet each other at a more or less distance, according to the curve of the diaphragm beyond the nozzle, and as they strike each other the direction of both changes and a wide thin fan-like spray is produced. The Iiat side of said spray is at right angles to the flat side of the converging spray of streams, as suggested by the dotted lines in Fig. 2. I havey also ascertained 'that by turning the concave side of the partition toward the supply of liquid the stream proceeds therefrom in the form of a thin sheet, which divides and breaks up or sprays as 1t leaves the passage F of the plug. The result is that the liquid is discharged in practically the same kind of spray, though the operation of producing the spray differs according to the side of the partition which is turned toward the source of supply.

The object of turning the plug in the manner indicated is that of utilizing the force of the stream to dislodge from the orifice such foreign substances as collect therein and as collect in the passage F. The length of the parallel slot I may be equal to the diameter of the passage F, if desired, and its width will vary with the general size of the nozzle and the Work it is to do. The essential characteristic lies in the slot and the partition, concave on one side and convex at the other side. I have used this device in connectionwith a spray-pump and have found that it operates in the manner herein described, and acc mplishes the spraying of liquid in a very satisfactory manner.

I am aware of and desire to disclaim a stopcock, the object of which is to regulate with precision the throw of minut-e quantities of fluids and preventing the escape of gas around the plug, the said plug having a transverse hole partly through it and a narrow approximately V-shaped incision through the remaining portion of its diameter. Sucha construction is not adapted to nor capable of my particular purpose-namely, that of causing the liquids ejected through the nozzle to assume the form of a iine spray.

Having thus fully described my invention,

IOO

the transverse passage, and having a passage partly through it, and a concave-convex par- 15 tition across the said passage and near one end thereof, With the convex side toward the farthest termination of the passage in the plug, substantially as described.

In testimony whereof I aliix my signaturein zo presence of two witnesses.

JOHN BEAN.
